So me and my bofriend have been dating for 7months. 2 years ago he dated a girl for 3years and she broke up with him after he moved almost an hour away. From what it seems like he really dislikes her and barley talks about her. But then I saw him going to search something on his Instagram and her username popped up as the last person he had looked up. Then the other day he had left a tab open on his laptop with her facebook page. I never confronted him about it but it makes me extremly insecure and as pathetic as it sounds i have cried about it because i feel like i can't compete. she has a boyfriend and she's happy and done with him but i feel like he's obsessed with her. I don't look at any of my exes on social media so is this actually normal? and why? have you ever gone through this?
